英文
tree grammar-
A sentence of a grammar is ambiguous if there exists two syntax trees for it.
如果一文法的句子存在兩個語法樹,那麼該句子是二義性的。Focusing on the function words, it recognizes all of the phrases which contain some function word, and analyzes the relationship of the phrases, to form the syntactic tree

句型的分析是某個推導(或許是其語法樹)的構造過程。According to the program structure of ansi c, some syntax - tree - nodes are designed in front - end, including function, block, data structure, type, expression, identifier and so on. syntax tree is divided into three levels, namely program level, function level and block level, which are useful for analysis of syntax and semantic in compiler as well as transferring syntax tree into rtl. retargetable compiler mainly includes intermediate representation, machine description and interface technique between compiler and machine description
編譯前端的實現技術包括詞法分析、語法語義分析和中間代碼生成技術等,針對ansic的程序結構,分別設計了函數、塊、數據結構、類型、表達式、標識符等語法樹結點,並將語法樹分成編譯層次、函數聲明和塊三個不同層次,使語法樹具有清晰的層次結構,有利於編譯程序的語法和語義分析,以及從語法樹到rtl中間表示的轉換。Aiming at this problem, the main research issues and achievements in this paper are as follows : bi - directional data transformation between rdb and xml with semantic constraints preserved for most of existing researches on static data transformation between xml and rdb, dtd is taken as the schema description language for xml, and the semantic constraints are often lost during the transformation process. to overcome these disadvantages, the author adopts xml - schema, a standard schema description language proposed by w3c to replace dtd, as the description method owing to its more powerful functions than dtd, and of course with the syntax much more complicated. after analyzing the constraints characteristics in both xml - schema and relational schema, a semantic constraints - preserved algorithm is proposed which can realize the bi - directional schema mapping between rdb and xml through a formalized description of xml based on regular tree and a general expression for relational schema based on direct graph approach
保留語義約束的xml與rdb雙向靜態數據轉換技術現有研究大多採用dtd ( documenttypedefinition ,文檔類型定義)作為xml的模式描述語言,並且在模式映射過程中丟失語義約束信息,本文分析了xml - schema ( xml - schema採用與dtd完全不同的語法,數據描述能力更強同時也更為復雜,已被w3c確定為替代dtd作為xml模式描述語言的標準)及關系模式的語義約束特徵,通過基於正則樹的xml形式化描述方法以及基於有向圖的一般關系模式表示方法的研究,建立保留語義約束的xml - schema與關系模式的雙向模式映射演算法,實現了xml與rdb的雙向數據轉換,較好地解決了xml與rdb在靜態數據轉換層面的數據集成問題,可有效滿足企業大量rdb數據面向xml的發布以及與日俱增的xml數據存入rdb的應用需求。Firstly, for the errors of text ’ character and word, utilizing neighborship of character or word, check character and word errors by character string co - occurrence probability. secondly, for the errors of syntax of text, according to statistic and analysis of a large - scale contemporary chinese corpus, recognize the predicate focus word and the others sentence ingredient, check the syntax errors. thirdly, for the errors of text ’ semanteme, establishing semantic dependency relationship tree based on hownet knowledge, presents a method that based on semantic dependency relationship analysis to compute sentence similarity, check the semantic errors
